Title: Improvements in or relating to electric discharge tubes
IPC: H01J61/00
Filed: 1934-06-25
Abstract: 424,322. Discharge apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. June 25, 1934, No. 18730. Convention date, June 26, 1933. [Class 39 (i)] An electric discharge tube contains a gas filling, an incandescent cathode, an anode, a window located on the opposite side of the anode to the cathode, and a quantity of a vaporizable substance located in that part of the discharge remote from the window, the pressure and intensity of the discharge being such that while in the neighbourhood of the cathode the vapour participates in the emission of light, between this portion of the discharge and the window a discharge takes place exclusively in the gas filling with a voltage gradient sufficiently high to prevent diffusion of the vapour towards the window. The discharge tube 1, Fig. 1, has an incandescent cathode 2, two anodes 3, 4 and a window 8. Vapour for magnesium 5 at 320-400‹ C., participates in the discharge near the cathode, but is kept from the window by a discharge of high voltage gradient in neon at 6 mms. pressure. The boundary separating the discharges is curved as shown in dotted lines, and to prevent leakage along the wall, small inwardly-projecting protuberances may be formed in the wall of the tube near the boundary, or an insulated metal gauze may be placed across the tube (Fig. 2, not shown). The tube is partly surrounded by an asbestos jacket, or by a reflecting sheet of metal. The jacket 6 incorporates a heating resistance 7 in series with the lamp. To prevent weakening of the envelope by the attacking vapour, a cylindrical or conical jacket 11, Fig. 3, preferably of heat proof material such as porcelain, alumina or magnesia, surrounds the cathode and the vapour discharge. The light passes to the window 15 through the ring-shaped anode 14. The jacket 11 may be of ferrochromium, polished internally, or of refractory material with an external reflecting layer of molybdenum, and an insulated metallic gauze within it may enclose the vapour discharge. Aluminium vapour at 900‹ C. may be employed as a source of ultra-violet rays, or silver vapour may be used. Numerical values of the spacing and dimensions of the electrodes are given.

Title: Apparatus for the production of twisted bread loaves
Inventor: HURTZ ERNEST GEORGE
IPC: A21C3/08
Filed: 1954-06-25
Abstract: 771,608. Dough-twisting machines. ATLAS EQUIPMENT (LONDON), Ltd. June 24,1955 [June 25, 1954], No. 18774/54. Class 87(2). When twisting two strips of dough together for making twisted loaves, the twisting movement increases progressively from one end to the other of the strips. The strips are fed successively along a conveyer belt 15 to a space 24. A first strip idles in the space 24 until it is joined by a second, when the friction and adherance between the two strips causes the strips to move with a rotating roller 17 to the annular space between a fixed table 2 and a rotating plate 8, where the strips are twisted together. The twist being greater at the outer parts of the strips due to their greater radial distance from the axis of rotation. The strips are removed from the end of the table which is inclined as shown at 4, Fig. 4, by a conveyer 14. The height of the plate 8 above the table and the inclination of the part 23 of the belt 15 may be adjusted. Resilient fingers 27 help to make the dough strips stick together. Air is blown by a fan 31 through slots 7 in an inner wall 6 to dry the dough and prevent it from sticking to the members 8, 2. The upper surface of the table 2 may be covered with canvas.

Title: Improvements in or relating to apparatus for lowering and raising ships' boats and other objects
IPC: B63B23/18
Filed: 1918-11-18
Abstract: 137,346. Anderson, A. Nov. 18, 1918. Driving-gear for winding and paying-out apparatus; self-sustaining gear; laying or guiding ropes on during winding.-A winch for raising and lowering ships' boats and other objects comprises a drum 1 with an internally screwed boss 3 mounted on a threaded shaft 2, the end 14 of the drum being adapted to engage with a friction clutch member 5 forming part of a hand or power operated gear-wheel loosely mounted on the shaft 2. The rotation of the shaft is controlled by a capstan handle 15, and, by the relative rotary movement between the drum and shaft, the drum is moved along the shaft until it engages with the friction member 5. By this arrangement, the drum may be moved until the clutch members are in engagement, and the falls are then wound on the drum by the rotation of the wheel 5. The load may be lowered by disengaging the clutch members, the lowering operation being controlled by suitably moving the drum laterally along the shaft by slowing the rotation of the capstan handle 15. This causes the friction clutch members to engage, and the wheel 5 being stationary acts as a brake. To raise the falls quickly, the pin 23 is inserted into a slot 24 to lock the shaft and drum together. The drum may then be rotated rapidly by the capstan handle 15. To ensure that the ropes are wound equally and uniformly, the drum is grooved and the falls are passed through eyelets 16 to which a traversing movement is imparted by means of a rotary screwed shaft 18. A second traversing-member presses the coils together on the drum. The driving-shaft 12 is prevented from running back by ratchet gear.

Filed: 1937-07-07
Abstract: 490,266. Locking valves. MYERS, L. L. July 7, 1937, No. 18855. [Class 135] A series of valves 14 fitted on the delivery manifold of a tank truck having several tanks or compartments have individual valve operating mechanisms, the operation of any one of which moves a sectional sliding bolt 35 which locks the remaining valve operating mechanisms against operation to open their respective valves. As shown the manifold is formed by the outlet chambers 17 of the valve casings 14 which are secured together and have inlet connections 11 corresponding to the number of tanks or compartments. Each valve member 26 is guided by ribs 29 and a spider 28 and has a depending stem 27 which can be engaged by a lever 32 mounted on a shaft 31 operable by a detachable external lever (not shown). Each lever 32 carries a latch finger 33 with a cam end 34 which when all the valves are closed lies opposite the correspondingly shaped ends of two adjacent sections say 36a, 36b of the locking bolt 35. The movement of any one of the fingers 33 when the valve corresponding is opened moves the sections of the bolt on its opposite sides apart against the action of spring plungers 38 so that the ends of the other sections are no longer opposite the corresponding fingers movement of which is therefore prevented. The movement of the bolt sections is limited by collars 39 engaging the bearings 36.
